How Does Adding Bleach Change the Hair Color Achieved from Darkening?
Adding bleach to hair that has been darkened can significantly alter the hair color. Bleach works by removing the natural color pigments from the hair. When you darken hair with dye, you deposit color into the hair shaft. If you then apply bleach, it effectively strips away both the dye and the natural pigments.
The process begins with the bleach lightening the hair. This occurs through a chemical reaction that breaks down color molecules. The darker the initial color, the more bleach is needed to achieve a lighter shade. Consequently, this can lead to an unpredictable final color. The hair may turn brassy or uneven if the dark pigment is not fully neutralized.
Additionally, bleach can damage hair due to its harsh chemicals. It alters the hair’s structure, making it more porous and fragile. Therefore, hair may become dry, brittle, or more prone to breakage. Conditioning treatments can help restore some moisture, but care is essential to maintain hair health.
In summary, adding bleach after darkening hair changes the color by removing both the dye and natural pigments, resulting in a lighter but potentially damaged appearance. Proper care during this process is crucial for sustaining hair health.
